This is really strange - if our Windows 2000 servers are booted with a date greater than 27 July 2005 then the following happens:
Network connections icon gone from taskbar, network connections missing from folder, Symantec antivirus server disabled, tape drives shown as offline in veritas backup exec, add/remove program does not allow programs to be removed, no access to Internet.
Boot with a date prior to this then change date to realtime date after login and no problems, multiple logoffs/logins after that ok, so it's something that kicks in at machine restart. The problem also affects some Windows XP machines. I restored a Win XP workstation back to a backup from 27 Dec 2004, booted with correct date (disconnected from lan) and same problem.
I have tried multiple anti virus products and spyware detection - nothing. Searched google etc - nothing, it's like it doesn't exist. Checked obvious registry setting (e.g run) - nothing. Checked system policies, but nothing shown as stopping access to Network connections etc.
Win 2k servers are at SP4 with latest roll-up installed, Win XP are SP2 with all current fixes.
This one is driving me crazy - any ideas would be great.
